What else can I help you with?
Why is the boiling point of NaCl higher than sucrose?
Nacl is a salt and forms ions in the solution Na+ Cl- , in other words it has 2 molecules dissociated. On the other hand Sucrose does not dissociate it stays as one mole of sugar. This is why the boiling point of Nacl is higher then Sucrose.
How many atoms of chlorine are in 2.00 moles of CCl4?
The number of chlorine atoms in 2,00 moles of CCl4 is 48,113.10e23.
Why iodine dissolve readily in CCl4?
Iodine dissolves readily in CCl4 due to the presence of London dispersion forces between the iodine molecules and the non-polar CCl4 molecules. These weak intermolecular forces allow for iodine molecules to be dispersed throughout the CCl4 solvent.
Is H2O more dense than CCL4?
No, CCl4 (carbon tetrachloride) is more dense than H2O (water). The density of H2O is 1 g/cm3, while the density of CCl4 is 1.59 g/cm3.
What mass of CCl4 is formed by the reaction of 8.00 g of methane with an excess of chloride?
The balanced chemical equation for this reaction is: CH4 + 4Cl2 -> CCl4 + 4HCl. From the equation, it can be seen that 1 mole of CH4 produces 1 mole of CCl4. Therefore, 8.00 g of CH4 would produce 8.00 g of CCl4.
How much viscosity in cf4 ccl4 and cbr4?
CF4 has the lowest viscosity, followed by CCl4, and then CBr4. This is because viscosity is generally higher for heavier molecules due to stronger intermolecular forces that inhibit molecular motion.
Would H20 or CCl4 be expected to have a higher melting point?
Boiling point you mean, and H20 has a higher BP
Is CBr4 more volatile than CCl4?
ch4 is the most volatile
What has a higher boiling point CH3CH3 or CH3Cl?
CH3Cl because it is polar meaning it has both a dipole-dipole bond and dispersion bond, where as CCl4 is non polar and only has a dispersion bond. Since CH3Cl is bonded together stronger, it will be harder to break up and therefore a greater temperature will be required to boil it Edited (9/20/10) CCl4 has a bp 76.7 C, CH3Cl has a bp -24.2 C, see wikipedia or MSDS info. That means the first answer is wrong. Boiling points are based on intermolecular forces. Stronger the forces, lower the vapor pressure, higher the bp. The reason CCl4 has a higher boiling point is because dispersion forces increase with increasing molecular weight and # of electrons. Therefore the greater number of electrons in CCl4 create a stronger dispersion force than the combined dipole+dispersion forces in the CH3Cl.
Why does H2O have a higher melting point than CCl4?
It has to do with intermolecular forces. H2O has an oxygen with two hydrogens coming off of it. This forms two hydrogen bonds, which are much stronger than the London Dispersion Forces in CCl4. (Since CCl4 is non-polar, there are no Dipole-Dipole forces).
Why is the boiling point of carbon tetrachloride greater than silicontetrachloride?
tetrahedral molecules will have a better packing if the central atom is smaller than the peripheral ones. hence carbon tetrachloride has better packing and hence a higher boiling point. (this is most probably wrong, but seemed like a only explanation i could think of)
What is the molar mass of adrenaline in a solution of 0.64 g of adrenaline in 36.0 g of CCl4 elevates the boiling point by 0.49?
First, calculate the molality of the adrenaline solution in CCl4 using the elevation in boiling point. Then, determine the moles of adrenaline in the solution using the molality and mass of CCl4. Finally, divide the mass of adrenaline by the moles to find the molar mass.
What is the equation of methane and bromine without the presence of sunlight?
The reaction is:3 CCl4 + 4 AlBr3 = 3 CBr4 + 4 AlCl3
What is the boiling point of C2H5Cl?

When CCl4 boils what is inside the bubbles?
when any liquid BOILS the bubbles just contain the same substance, but just as a gas.now why did I put 'boils' in capitals?you know if you boil water there are tiny bubbles already forming before it is actually boiling. these are the gasses which were dissolved in the water.
Molecular compounds boil at much higher temperatures than do ionic compounds true or false?
This is false. Ionic compounds have higher boiling points than molecular compounds. For example, the boiling point of the ionic compounds copper(II) oxide, CuO, and sodium chloride, NaCl are 2,000 degrees C and 1,413 degrees C, respectively. The boiling point of the molecular compounds carbon tetrachloride, CCl4, and water, H2O are 76.72 degrees C and 100 degrees C, respectively.
Does H2O have a higher melting point than CCl4?
Yes. Water melts at 0 ºC. Tetrachloromethane (Carbon tetrachloride) has a melting point of -22 ºC
